FM 27-5 United States Army and Navy Manual of Military Government and Civil Affairs 1943-12-22
"Military necessity in the conduct of operations as well as the obligation upon invading forces under international law requires that such forces institute military government in occupied areas.
This manual states the principles which serve as a general guide for the War Department, the Navy Department, theater commanders, and their subordinates in planning and exercising, military government and control of civil affairs in territory occupied by forces of the United States. It is for the use of the Army and the Navy, whether they are acting alone, jointly, or in concert with forces of allied countries. Such terms as "commanding officer," "military," and "forces" have reference to either or both branches of the service."
